Pop-free clipping ensures that clipped primitives are still valid and visible if crossing a clip volume boundary rather than just being discarded. This pop-free clipping support in turn fixes a number of dEQP OpenGL ES 2 test case failures that had been observed on R300 through R500 (Radeon X1000 series) graphics cards.&#13;<br \/>\n<\/p>\n<p align=\"center\"><a href=\"https:\/\/www.phoronix.com\/image-viewer.php?id=2025&amp;image=christmas_r300_1_lrg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/12\/1766539833_734_image\" alt=\"Radeon X1800XL graphics card\"\/><\/a><\/p>\n<p>This pop-free clipping is based on <a href=\"https:\/\/gitlab.freedesktop.org\/mesa\/mesa\/-\/commit\/df2c774a83765d63a487e0f72f91021ccdf06533\" target=\"_blank\" rel=\"noopener\">this R600 driver commit<\/a> from another community contributor earlier in the year that in turn was based on newer code from the RadeonSI driver used by Radeon GCN and newer graphics cards.<\/p>\n<p align=\"center\"><a href=\"https:\/\/www.phoronix.com\/image-viewer.php?id=2025&amp;image=christmas_r300_2_lrg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/12\/1766539838_776_image\" alt=\"ATI R500 class graphics cards\"\/><\/a><\/p>\n<p>Pavel opened up <a href=\"https:\/\/gitlab.freedesktop.org\/mesa\/mesa\/-\/merge_requests\/37977\" target=\"_blank\" rel=\"noopener\">this merge request<\/a> two months ago to land the pop-free clipping support for R300g. This code was since tested across various R300\/400\/500 graphics cards. After working through some issues, the code was merged yesterday just in time for the Christmas holiday season.<\/p>\n<p>It&#8217;s increasingly rare seeing Mesa R300 Gallium3D driver activity for those 20+ year old graphics cards, but occasionally bug fixes and new feature work such as this pop-free clipping still come about thanks to the open-source nature of the drivers and still living within the Mesa driver tree. This now-merged R300g work will be found in Q1&#8217;s Mesa 26.0 feature release.<\/p>\n","protected":false},"excerpt":{"rendered":"If Linux 6.19 switching from the Radeon legacy to AMDGPU kernel drivers for the GCN 1.0\/1.1 GPUs for&hellip;\n","protected":false},"author":2,"featured_media":651519,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[2228,2227,2225,2224,2231,2229,2226,2230,2223,2234,53,2232,2233,16,15],"class_list":{"0":"post-651518","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-desktop-linux","9":"tag-linux-benchmarking","10":"tag-linux-hardware-benchmarks","11":"tag-linux-hardware-reviews","12":"tag-linux-how-to","13":"tag-linux-performance","14":"tag-linux-server-benchmarks","15":"tag-open-source-graphics","16":"tag-phoronix","17":"tag-phoronix-test-suite","18":"tag-technology","19":"tag-ubuntu-benchmarks","20":"tag-ubuntu-hardware","21":"tag-uk","22":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115771961326922001","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/651518","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=651518"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/651518\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/651519"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=651518"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=651518"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=651518"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
